• Make sure that you have set it to its native resolution. Check the user guide to determine what the native resolution of the display is and set it to the native resolution if  the video source that is being used can support it. Digital signals (HDMI, DisplayPort) normally produce sharper images. If you are using a VGA or analog signal try to switch if possible.
  • Make sure the refresh rate is set to 60Hz.
  •  If you are using an Extension video cable, KVM switch, or video splitter box, these can affect the image. Connect the monitor directly to the PC to see if there is an improvement in the image.
  • If projector has a focus ring, please adjust it to optimum image quality.
